Radiation dose from cardiac computed tomography before and after implementation of radiation dose-reduction techniques.
CONTEXT Cardiac computed tomography angiography (CCTA) can accurately diagnose coronary artery disease, but radiation dose from this procedure is of concern. OBJECTIVES To determine whether a collaborative radiation dose-reduction program would be associated with reduced radiation dose in patients undergoing CCTA in a statewide registry over a 1-year period and to define its effect on image q...
متن کاملReducing Radiation Dose in Pediatric Diagnostic Fluoroscopy.
PURPOSE To assess radiation dose in common pediatric diagnostic fluoroscopy procedures and determine the efficacy of dose tracking and dose reduction training to reduce radiation use. METHODS Fluoroscopy time and radiation dose area product (DAP) were recorded for upper GIs (UGI), voiding cystourethrograms (VCUGs), and barium enemas (BEs) during a six-month period. The results were presented ...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Within the past 20 years, the radiographic examination in the medical field has increased by a factor of about 3 to 5 times, while the total radiation dose has increased by a factor of about 200-400. This has ascribed to the rapid increase in CT usage (1). T...
متن کاملBCC and Childhood Low Dose Radiation
Skin cancer is a late complication of ionizing radiation. Two skin neoplasms prominent Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC) are the most famous complications of radiotherapy. Basal Cell Carcinoma (BCC) is the most common human malignant neoplasm. Many genetic and environmental factors are involved in its onset. BCC is observed in sunexposed areas of skin. Some patients w...
متن کاملLow-dose radiation exposure and carcinogenesis.
Absorption of energy from ionizing radiation by the genetic material in the cell leads to damage to DNA, which in turn leads to cell death, chromosome aberrations and gene mutations. While early or deterministic effects result from organ and tissue damage caused by cell killing, latter two are considered to be involved in the initial events that lead to the development of cancer. Epidemiologica...
